Hi,

I'm trying to add a custom control to an xml-defined dialog. I'm using
this code snipplet in the xml file:

[ ... ]
<object class="sizeritem">
<object class="unknown" name="foobar">
</object>
</object>
[ ... ]

After reading the dialog from the xml file via wxxrc, how do I add the
custom control to the widget tree ? By the way, is there a documentation
or faq for wxxrc ? The readme in contrib/src/xrc is somewhat outdated...

Bye,

Use AttachUnknownControl:

PreferencesDialog::PreferencesDialog(wxWindow *parent)
{
wxTheXmlResource->LoadDialog(this, parent, _T("preferences"));
wxTheXmlResource->AttachUnknownControl(_T("tm_langs"),
new wxEditableListBox(this, -1, _("My Languages")));
}

This is relatively new stuff, so make sure you have post-2.3.1
version of XRC, preferably fetched from CVS trunk. (Older versions
had broken "unknown" support that didn't work at all.) You may call
AttachUnknownControl anytime, not neccessary immediately after
LoadDialog.

No, unfortunately not yet. The best sources are, for now
- files generated by wxrcedit, XRCEd or wxDesigner
- poEdit, an application that uses XRC (http://poedit.sf.net)
- XRC sources
- this mailing list archive
Roughly in this order.
